MC-30 Bitumen: Low-Viscosity Medium-Curing Cutback Bitumen for Prime Coat and Road Base Preparation

MC-30 Bitumen is a type of medium-curing cutback bitumen with low viscosity, composed of penetration grade bitumen blended with a petroleum solvent (kerosene). With a kinematic viscosity of 30 to 60 mm²/s at 60°C, it is the most fluid type of medium-curing cutback bitumen. The solvent in this bitumen temporarily reduces the viscosity for easier application, and after use, it evaporates, leaving the bitumen to perform its primary function. iranrequest., utilizing advanced refining technology, produces and supplies this product with quality conforming to ASTM D2028-97 standard.

Manufacturing Excellence and Innovation

iranrequest  MC-30 Bitumen is produced through precise blending of approximately 58% penetration grade bitumen with 42% kerosene. The production process is carried out under strict temperature control and using advanced equipment, resulting in a uniform product with consistent properties. This type of bitumen, due to its low viscosity, has exceptional penetration capability, making it highly suitable for prime coats and road base preparation.

Key Features and Benefits

• Very Low Viscosity: With a kinematic viscosity of 30 to 60 mm²/s at 60°C, it provides excellent penetration.
• Deep Surface Penetration: Due to its low viscosity, it easily penetrates into pores and fine cracks of surfaces.
• Excellent Adhesion: Creates appropriate bonding between the base layers and asphalt pavement.
• Suitable Curing Time: Curing time of approximately 48 hours allows sufficient penetration into the surface.
• No Heating Required: In warm seasons, it does not require heating and is easily applicable.
• Compatibility with Various Weather Conditions: Can be used in diverse weather conditions.
• Standards Compliance: Fully compliant with ASTM D2028-97 (reapproved 2004), ensuring global quality assurance.

Primary Applications

MC-30 Bitumen, due to its low viscosity and high penetration, has specific applications in the road construction industry:

• Prime Coat: Its primary use is as a prime coat on granular and aggregate bases before asphalt overlay, bonding the granular material of the base to the asphalt layer.
• Stabilization of Granular Layers: Penetration into granular layers stabilizes and bonds particles together.
• Waterproofing Surfaces: Creates a waterproof layer on various surfaces to prevent moisture penetration.
• Filling Voids: Fills capillary voids and fine cracks in surfaces.
• Cold Mix Asphalt Production: Used in preparing cold asphalt mixtures for road repair and maintenance.
• Bituminous Paints: Used as a base for producing bituminous paints and protective coatings.
• Cold Weather Applications: Suitable for use in cold weather conditions where pure bitumen cannot be used.

Technical Specifications

MC-30 Bitumen has the following technical specifications, meeting the precise ASTM D2028-97 standards:

Packaging and Delivery

MC-30 Bitumen is packaged in two ways to provide suitable options for different logistical needs:

Bulk in Tanker

This product can be shipped in bulk in special tankers for petroleum products for large projects.

New Steel Drums

For smaller orders, this product is packaged in thick, new steel drums on pallets to prevent any leakage inside the container.

Application Method

MC-30 Bitumen is typically sprayed onto the target surface using a distributor. It is recommended that:

1. The target surface should be clean and dry.
2. The ambient temperature during application should be at least 10°C.
3. The spray rate is typically between 0.5 and 1.5 liters per square meter, depending on the porosity of the surface.
4. After spraying, allow at least 48 hours for drying and solvent evaporation.
5. Prevent vehicle traffic until completely dry.

Safety and Precautions

The following safety notes should be observed when using MC-30 Bitumen:

• Refer to Safety Data Sheets (SDS) before use.
• Transport, use, and store at the lowest temperature possible.
• Eliminate all potential ignition sources during application.
• Avoid breathing vapors and avoid contact with skin.
• Always wear appropriate Personal Protective Equipment (PPE), including heat protection when used hot.
• DO NOT allow product or washings to enter stormwater or sewer systems.
